UNITED sTATEs GAS STOVE.

Application led Octbber 15, 1926. Serial No. 141,729.

My invention relatesoto an improvement 1n gasstoves wherein 1t 1s designed to pro- *videv a safety construction for the gas stove.

so that it is practically impossible to turn a on any of the burners of thegas stove withv gas stove owing to the fact that the burner out lighting the burner turned on.

A feature of my invention. resides in means for selectively and automatically lighting any particular burner by turning it on, the

lo act of turning on the burner automatically lighting the same.

A feature of my invention resides in means for automatically lighting the oven burner of a gas stove by simply turning on the valve which controls the flow of gasto the oven and which automatically operates lighting means to light the gas of the `oven burner bythe actof turning'on the gas to the same. This is an important feature of my invention as it provides a gas stove having thev advantage Iof overcoming the unde-` sirable feature of making it .necessary to light the burner of the oven with a match or other lighting means. In so far as I know, this is an entirely novel and new idea which is adapted lto overcome the detrimental features of lighting 'a gas oven, which cause more or less of a small explosion when being lighted, due to the volume of gas which is necessary to be directed to the oven burner and the gas channel whichis ordinarily used associated with gas oven burners. My inven. tion obviates the necessity of the gas channel for gas oven burners so that they canbe.

' lightedthrough the channel and provides a simple yet very leffective means of .automatically lighting the burner of the oven without opening the oven and Without the usual` puti which so commonly occurs inthe igni- 40 ion of surplus gas when the oven burner is it. v

A My invention also includes the feature of supplying the gas for the vlightingof the oven burner from the oven burnervalve and gas arm or tube which-leads to theV burner proper.` In other words, I do not need a separate supply of gas for lighting the Qven burner, but by means of a feeder tubeextending from' the gas armleading from the valve to the burner, I supply gas to the feeder t'ube which isadapted to be autoihatically ignited in the act of turning the gas to the oven burner which directs a light to the oven burner which isprior t the gas reaching the outlets of the burner, so thatas soon as'the gas begins to escape from the oven lbur-ner outlets it isi-ignited by 'the feeder tube, thereby overcoming thelling of the ovenl with surplus gas before it is ignited.

While heretofore it has been quite objectionable to ladies to light the oven burner of a l would puff when it was lit due to the escape of excess of gas before theburner-ignites, my lighter entirely overcomes this, making it a pleasure to operate my gas stove 'inthe lighting of any of the burners which is selected as the burner desired.

Itis also a feature of my invention to provide means for igniting the gas burner automatically from one of the surface burners. so

that if it is desired to light the gas burnerfor the oven and the surface `burner is inv operation, that is, lit, it is only necessary toturn .on the gas valve for'the oven burner,

thereby automatically igniting the gas oven burner through thesurface burner. Inthis manner I provide means for lighting the. gas oven burner from a` surface burner, a feature which I believe is entirely new in so far as I know. l

v It is a feature of my invention to provide means for operating a pilot light on my gas stove automaticallyto direct the flame in a manner sothat any burner'may be nited and thereby selectively lighting the burners of the gas stove, and 'with this means of operating the pilot light I providela cam loperating member which is associated with the valve of the gas burners to automatically operate the pilot in the turning on of;

the burner. I includer in my invention `.means for permitting the burner to be turned down by turning the burner valve beyond the wide open position, thereby shutting olil the valvey to a pre-determined amount so ,that the burner can be readily l turned down without going out and with'out operating the pilot lighter. Thel pilot lighter is only turned on in lthe opening of the gas valve and in the complete closing of the same. v

A feature o'f the invention resides in providing means for automatically 'operating the pilot light todirect a li'ght or iame to the respective burner to be lit in advance of the directingof the gas to any particular burner. In this manner thereis no chance of escape of 'gas'from the burner without being ignited hy the automatic lighting means. These features, together with other details and peculiar arrangement of parts of my.

gas stove and other objects will be more clearly and fully set forth in the following specification and claims.

In the drawings forming part of this specification:

Figure 9 is a perspective view of an alternative form of the operating cam for the valves of my gas stove.

My gas stove 'A is adapted to include the surface burners B which are provided with the ordinary and well known gas` arms 1() extending from the gas valves 11. The gas valves 1l are connected lo the main gas Vfeeder pipe 12 which extends along the front.-

of the gas stove A in the ordinary and well known manner and which is vsupported by suitable brackets lil to the front of the stove A.

A primary feature of my invention is to provide a gas stove wherein any ol the burner.; may be lit autonnitically hy simply turning on the gas valves 1l. My gas stove A is provided with a pilot lighter 14 which is connected by the pipe 15 to the operating valve 16, while the valve 16 is connected to the main gas feed pipe 12.` l

The lighter14 is provided with a burner 17. which is formed with vgas openings '18 in a manner to maintain a .small pilot light beneath the hood 19 of the lighter 14 and when the valve 16 is operated the lighter 14 is adapted to project flames .auch 'as 20 to the respective burners B.

Each of the valves 11 of my gas stove A is provided with cam discs 22 which are secured to the bottom of the valve 11 in a. manner so that when the valve 11 is operated by the handle 23, the cam disc is rotated. The cam dise or member 22 is provided with a cam portion 24 which projects from the annular flange 25. The cam 22 is adjustably supported at the lower end of the valve l1 and is adapted to be positioned so that the valve may turn the cam 24 into Voperatingposition just before the valve 11` opens f-:ulliciently to direct a flow of gas to -tl1e to the valve 16 and supports the rod 26 inl a manner to be foatingly held directly below the cam discs 22. By means of a pair of slotted arms 29 which are secured to the brackets 13 the rod 26 is held on its ends against movement out of line with the cam members 22, and thus -when any, of the handles 23 are operated the cams 24 are adapted to operate the rod 26 to depress the same and thereby operate the valve 16, automatically directing the flame to the burners B selectively to that they may be lit automatically in turning on the gas. The valve cam members 22 are adapted to be so adjusted on the valves l1 that the cam 24 maybe ro.- tated in a manner to operate the rod 26,50 that the pilot light 14 is operated to project the flame to the burner just before the gas is directed to the same. Thus no gas can escape before the flame 2() is projected to the `respective burner and when the gas does come out of the burner the flame is there to light it immediately. In this manner practically no escape of gas is apparent in my gas stove.

I have illustrated in Figure 9 a. cam disc 22 which is provided with a. series of cams 24 or ears, which may be used in place of the single cam member 24 illustrated on the disc.; 22 which are connected to the valves 1l. It is to be preferred, however, to use a single caln 24 as illustrated in the figures under ordinar conditions.

A feature of my invention resides in permitting theturning of any of the burners down low without operating the automatic lighter means including the pilot lighter 14. I accomplish this by forming the valve 11 with the groove 32 extended beyond the quarter or 90fmove1nent which is ordinarily the construction of the regulargas stoves now in use in so far as I know. 4This permits the pin 33 which acts asa stop on the valve 11 to travelin the groove 32 beyond UU Y " thevcenter line 34, illustrated in Figure' 5,

which is the wide open position of the valve 11, and permits thepin 33 'to be turned over to the position illustrated-in dotted outline direction to the closing of the burner ordiin Figure with the handle 23 beyond the center line 34 "and -moved in the opposite narily when it isdesired to shut the burner ofi'. By this means I may turn'down any of the burners without'operating the lighter 14 and it .also permits me to provide a coni struction of gas stove wherein the housewife turning down of the burner to a point where v it will still remainllighted, and not to a point of 90 so as to shut off the valve 11.l I have found this a very desirable feature 'm my gas stove.

My invention also includes -a gas stovewherein the oven burner C is adapted to -be automatically lit -by turning on the ovenburnervalve 11 whichdirects gas to the gas arm 36 in ay manner to feed gas to the burner C.

I have illustrated in the drawings the oven E cut away so as to C within the same.

The gas arm 36 is provided -with a gas lighter feeder pipe 37which projects from the elbow portion 36 of thefarm 36v in a clearly show the burners manner so "thatwhen gas is turned vlinto the gas arm 36 it will'extend into the gas lighter feeder 37. `The gas lighter feeder 37 is formed'wi-th ai series of small holes 38 extending from the upturned end 39 which is covered by the protecting hood which protects the feeder 37 from Ianything falling onto the same which mightordinarily clog the openings 38. The feeder lighter 37 extends from the arm 36 through an elongated opening 41 leading into the oven E with the inner end42 of the light 37 extending close to the openings 43 of the' burner C. It will end 42 to be noted from Figure 6 that Athe lighter' feeder 37 is formed in a manner so as to extend upwardly at 39 to support the hood 40 and the small openings 38 extend up the side ofthe upturned end 39 and then along toward the pnd 42 of the feeder 37,- but in a spiral-like (direction so as to bring the openings 38 out pn approximately the top of the mme readily direct a flame to the burner C.

The hood 40 also inclines tohold the gas about the upturned end 39 of the feeder 37 so that when the valve 11 is operated and a iame is directed from the lighter 14 to the light 37 and beneath the hood 40, as soon as the gas is fed from the gas arm 36 to the feeder 37 it will be ignited and will creep along the opening 38 .to the end l42, automatically. and practically immediately .lighting the gas as it escapes from the openings 43 of the burner C. Thus the burner C is lit automatically by the operation o-f the- -valve 11 without any puff or small explosion which is ordinarily the case in lighting gas Voven burners and which is quite objectionable to the'housewife. The ordinary light-l ing 'of the gas oven burners is even dreaded by some housewives as it often makes a small explosion as a large amount of gasis lighted.

With my inventlon this is entirely overously lights the oven burner .C with the turning on of the valve '11. It can be readily appreciated the importance of this lighting of the oven together with the lighting of the burners selectively and thereby providing a gas stove which is adapted' to fill a long felt want.

The oven burner C may be lighted by the lighter 37 picking up a light from one of the burners B which isformed with a series of openings 44 extending over the end of the same as illustrated in Figure 8 and in a manner to pro]ect a flamei beneath the hood 40 which is adjacent to one of the burners.

The hood and lightmay extend in close proximity to one of the burners B as illustrated in Figure 8 and thus the flame from the opening 44 is adapted to automatically light the feederA 37 when the valve 11 fnr the oven burner C is turned on and thereby automatically light the oven burner without the necessity of the lighter or pilot'such as 14.

My feeder 37 may be used as a simmer,A that is, the end 39 with the hood 40, as some heat will be directed up from the same at the same time'that the oven burner C is in oper-v ation. This provides a feature to the invention eliminating the necessity of a separate valve for vthe simmer as is sometimes the case with some constructions of gas stoves. l

The operation of my gas stove A is very 'simple andvof a practical nature as it provides .a safety gas stove wherein it is practically impossible for children to turn on thel valves 11 without lighting the burners B or the burners C and vthereby providing a safety gas stove for the home which is to be greatly preferred over the construction' of` vstove where the burners are not lit in this 4 utensil in the other hand. This is not true with the ordinary lighting means for gas stoves in so far as I kpow.

In accordance with the patent statutes I luive'described the principles of operation of my gas stove and while I have illustrated a particular formation and constructhm in the drawings adapted to be associated ivith the burners and of a particular construction ot burner valves and burners, l desire to have it understood that the same is only illustrative and that my invention may be carried out by other means and applied to uses other than those above set Yforth without departing from the spirit of my invention.
